Chargers second half

Caulcrick just fumbled after breaking three tackles in a gritty run two plays earlier. San Diego recovered.

Jarrett Brown is in the game at quarterback.

Ricky Jean Francois is playing outside linebacker. Curtis Taylor, who’s really on the bubble, made a great tackle and caused a fumble. He needs that.

The 49ers should lose this game. David White just told me that since 1990 37 teams went undefeated in the preseason and 19 did not make the playoffs. It includes two 49ers that went undefeated and made the playoffs.

49ers drive: TD Caulcrick on a 2-yard score. 49ers 17-14.

49ers drive: One of the great 49ers flops of all time. Nate Davis sold a push to the ground and got the call for unnecessary roughness. There’s a big play, Davis to Jurovich to get the 49ers to the 10. Michael Robinson would get a lot more yards if he ran with his head up.

49ers drive cont: Time out called by Davis. Before that, Davis darted out of bounds instead of trying to run through a tackler, something he was criticized for by Mike Singletary.

49ers drive: The Chargers are giving the 49ers passing game no respect at all. On non-third downs, they don’t have anyone 10 yards off the ball. Ouch, Cody Wallace with another personal foul, but the 49ers are still get a first down. Wallace is staying in the game.

49ers drive: A personal foul by Cody Wallace dooms the drive

Chargers drive: Running back Curtis Brinkley just scored a 2-yard touchdown after a long pass completion against Karl Paymah. It brings up the question – who the heck is the nickel back on this team? 14-10 Chargers. It would be good to see Davis put together a drive on the next possession.

49ers drive: Long pass to Kevin Jurovich was intercepted by Bennett. It looked like Hughes interfered, but he did out-fight Jurovich for the ball. Nate Davis is having a bad outing.

There goes a 90-yard punt return for a score by the Chargers. It’s now 10-7.

49ers drive: Anthony Dixon has sore ribs and his return is probable. A three out under Nate Davis.

Chargers drive: San Diego ran seven straight times. Fullback Billy Lasko is blowing up linebackers on the runs, including Bowman. Taylor Mays is taking command out there, he was telling Bruce Davis where to go. The 49ers force a punt.

49ers drive: Nate Davis doesn’t look sharp. He’s playing like a guy who doesn’t seem to know the playbook very well. The 49ers forced to punt.

The second half of the last preseason game is always tricky. The team has to make the decision, do they go with players they are going to cut? Because if they do, it means they would have to pay an injury settlement to release them. The 49ers, so far, in this game, don’t seem to care about that.
